Abstract
The aim of the study was to determine productivity of hybrid winter rye under low sowing densities. The experiment was conducted on soil classified as a very good rye type. Four sowing densities (100, 150, 200 and 250 grain/m2) were tested on background of different nitrogen doses (0–160 kg N·ha-1). The lowest density (100 grain/m2 ) resulted in the grain yield reaching 5.5 t·ha-1. Increase of sowing density influenced yield weakly, below 0,5 t·ha-1. Interaction between sowing density and nitrogen fertilization was not confirmed. The highest yield was obtained at 120 kg N·ha-1.
